| Summary: | Data reported by supervisory control and data acquisition (SCADA) systems is critical for evaluating the as-operated performance of a facility. Typically these systems are designed to support specific control domains, but facility performance analysis requires the fusion of data across these domains. Since a facility may have several disparate, closed-loop SCADA systems, resolution of data interoperability issues (heterogeneities) is a prerequisite to cross-domain data fusion. There are no general methods for resolving these heterogeneities in the context of a nonproprietary core building information model (BIM) format. This article describes how these standard data models are applied to a general framework for the integration of building information models and building sensor telemetry. Given the number of very large corporations, each with its own research agendas and proprietary products, and the large number of installed buildings, each with its own control systems, yet another control scheme or technology will not make an impact on improving this market. The authors propose solutions to these underlying data heterogeneities by adopting existing data standards and introducing new data schemas (only when necessary) based on consensus between industry, government, and academic stakeholders. The Industry Foundation Class (IFC) 2X4 controls domain is the foundation of the authors’ decomposition of SCADA systems as components, assemblies, and connections that relate to other objects in the facility. The Open Building Information eXchange (oBIX) provides the basis for the authors’ representation of raw telemetry streams that map to the underlying IFC model. The system concept described in this article is part of an effort that is expected to produce an Industry Foundation Class Model View Definition (MVD) for building SCADA systems, product type templates for building SCADA products, the architectural design of an integration platform, and the specification of common predictive and analytical functions for deriving usable intelligence from the integration framework. |
